A dissolved gas analyzer (DGA) is a diagnostic tool used to detect and measure gases dissolved in transformer insulating oil. These gases—such as hydrogen, methane, ethylene, acetylene, carbon monoxide, and carbon dioxide—are generated from oil degradation due to thermal and electrical stresses. DGA identifies incipient faults like partial discharges, arcing, or overheating before they lead to catastrophic failures. Methods include gas chromatography, photoacoustic spectroscopy, and others, with devices ranging from portable units to online monitoring systems. Early detection enhances transformer reliability, prevents outages, and supports predictive maintenance in power utilities.

Market Overview

The Europe dissolved gas analyzer market is forecasted to grow at a CAGR of 6.9% from 2023 to 2030. This expansion is propelled by increasing investments in utility infrastructure, heightened awareness of DGA benefits for fault prevention, and rising electricity demand amid urbanization and grid modernization.
